In addition, assume that no travel is possible between source nodes, between intermediate nodes and between destination nodes and no direct travel from source nodes to destination nodes. Let the source nodes be labeled as 1, 2, and 3, the intermediate nodes be labeled as 4 and 5, and the destination nodes be labeled as 6 and 7. If there are 300 units available at source 2, state the constraint for source node 2.
